city, Cumberland county, southwestern New Jersey, U.S. It lies at the head of navigation on the Maurice River, 45 miles (72 km) south of Philadelphia, Pennsylvania. Union Lake, formed by a dam (1806), is to the northwest. The earliest settlers were woodcutters who built cabins along the riverbank in the late 1700s. Once a part of Maurice River and Fairfield townships and known successively as Shingle Landing, Maurice River Bridge, and The Bridge, the town was laid out by Joseph Buck, who named it for the local mills.

Millville is an industrial centre that uses the vast local silica deposits for glassmaking (glass). Its first glass factory, established in 1806 by James Lee, influenced and encouraged American glass manufacturing throughout the 19th century. The city's Wheaton Village includes the restored glass factory of the doctor T.C. Wheaton (1880s), a one-room schoolhouse (1876), and a glassware museum. The city's other manufactures include aircraft parts, plastics, and textiles. Inc. town, 1801; city, 1866. Pop.
